Sustainability Assurance

There is a lot at stake for you and your investors, customers, banks, ratings agencies, employees, and society at large.

Your stakeholders want to see transparency and progress—and high-quality ESG and climate disclosures published in accordance with recognized ESG standards and frameworks. Let us empower you during this critical time to become leaders in transparency through independent assurance.

We offer:

  • External ESG reporting and Assurance readiness – Understand the governance, risks, processes and controls you have in place for ESG data and metrics and reporting therein, and provide recommendations for improvement
  • Assurance frameworks – assure once for many – as shareholders, banks, ratings agencies, green bond holders and others require more assurance how can you do that in a robust and efficient way
  • Assurance review – Limited assurance over select ESG metrics or report as a whole
  • Assurance examination – Reasonable assurance over select ESG metrics or report as a whole

These services may improve your ability to meet stakeholders’ expectations for accurate and reliable disclosures while helping to reduce risks related to misleading or omitted disclosures and avoiding non-compliance with laws and regulations. Obtaining assurance also gives management and the board greater confidence in the completeness and accuracy of your ESG disclosures to enable them and to be confident in what they are representing to the various stakeholders.
